Numerical study of the attenuation properties of viscoelastic metamaterials
(
Institute of Physics Publishing
, 2018 , Conference Paper)
Metamaterials (MMs) are materials engineered to have a property that is not found in nature. In this study, one-dimensional MMs is investigated, particularly that with a functional elastic wave band gaps where propagation ...
Experimental study of the attenuation properties of metal-viscoelastic bi-layered materials
(
Institute of Physics Publishing
, 2018 , Conference Paper)
Phononic crystals (PCs) are multi-layered materials with functional elastic wave band gaps where propagation of vibration within these band gaps is restricted. PCs have vibration attenuation properties dependent on their ...
Proactive power allocation and caching node selection for regular service guarantees
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
This paper studies the potential of proactive resource allocation to prolong the communication sessions in networks with limited energy budgets and stringent quality-of-service (QoS) requirement, particularly a regular ...
Security Performance Analysis of MISOSE Transmission with Random Unitary Beamforming
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
Random unitary beamforming (RUB) is a multiple antenna transmission scheme requiring limited channel state information (CSI) with low computational complexity. In this paper, we investigate the security performance of RUB ...
Physical Layer Security Analysis of UAV Based Communication Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
In this paper, we investigate the communication security in aerial wiretap channels, where a network flying platform (NFP) wishes to send information to a legitimate destination, in the presence of multiple eavesdroppers. ...
Performance evaluation of an on-board integrated battery charger system using a 12-Slot/10-pole surface-mounted PM propulsion motor
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
The concept of Electric Vehicles (EVs) withonboard integrated battery chargers, which can be directly connected to the three-phase ac mains, has recently emerged as a cost effective and a practical alternative to charging ...
Axial pull-out response of a small-scale concrete pile subjected to cyclic thermal loading in sand
(
American Society of Civil Engineers (ASCE)
, 2018 , Conference Paper)
Energy piles support structural loads and exchange heat with surrounding soils using closed-loop ground source heat pump (GSHP) systems. A GSHP connected to an energy pile operates in cycles where it functions for a period ...
Stateless Security Risk Assessment for Dynamic Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
Emerging networking technologies, such as cloud and Software Defined Networking, provide flexibility, elasticity and functionalities to change the network configurations over time. However, changes also impose unpredictable ...
OCR-based hardware implementation for qatari number plate on the Zynq SoC
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
Automatic Number Plate Recognition (ANPR) systems have become widely used for safety, security, and commercial purposes. A typical ANPR system is based on three essential stages: Number Plate Localization (NPL), Character ...
Optimal PMU placement for large practical systems Qatar grid as an example
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
Phasor Measurement Unit (PMU) is a measurement devices capable of providing measurements with high accuracy, but due to its high cost it is desired to find the optimal placement for them. This paper tries to address the ...
